SSH Key Fingerprint

See more SSH Key Examples

Generates a fingerprint for an SSH key. Ruby

require 'chilkat'

success = false

key = Chilkat::CkSshKey.new()

# Load an SSH key from an encrypted OpenSSH-formatted private key:
key.put_Password("secret")

# First load the PEM into a string:
keyStr = key.loadText("privkey_openssh_encrypted.pem")

# Import into the SSH key object:
success = key.FromOpenSshPrivateKey(keyStr)
if (success != true)
    print key.lastErrorText() + "\n";
    exit
end

# Generate the fingerprint:

fingerprint = key.genFingerprint()

print fingerprint + "\n";

# A sample fingerpring looks like this:
# ssh-dss 2048 d0:5f:f7:d6:49:60:7b:50:19:f4:41:59:d4:1f:61:7
